Abstract: Performance of endpoints, client devices and servers within a communication system, is monitored by collecting call quality data from each endpoint. The collected metric data is retrieved periodically from a database, categorized based on endpoint location and metric type, and compared to predefined thresholds for different endpoint types, metric categories, and call configurations. If an alert condition is met indicating a problem with quality of experience in the system, an alert is issued to an administrator.

Abstract: User quality of experience in a real time communication system is determined by analyzing endpoint performance metric reports correlated with performance factors of each endpoint in an endpoint profile for a more complete view of an audio/video quality of experience. Reports may include endpoint profile reports, which may be sent once at the beginning and then again only if an endpoint attribute changes; session reports, which include measured metric information and are sent at the conclusion of each session; and session interval reports, which also include metric information, but are sent during the session based on a period or a predefined threshold.

Abstract: Performance of endpoints, client devices and servers within a communication system, is determined by collecting call quality data from each endpoint by a quality monitoring server/application. Call quality data includes predefined metrics based on network and end device characteristics during each call. Calls include voice, video, and data exchanges. Collected metric values are then aggregated according to a formula for consistency and scaled based on factors such as traffic volume. Resulting performance values are used to order the endpoints such that those with degraded quality and prioritized based on factors like traffic volume can be attended to first.

Abstract: End-to-end testing of a communications network, specifically a unified communications network, is accomplished by employing one or more sets of agents controlled by one or more organizers. Agents, capable of initiating, emulating, and recording various aspects of communication, are deployed such that call can be made through a wide range of network paths. Test scenarios defined dynamically based on network conditions or based on administrator input are executed by an organizer, which directs the agents reporting to it. Collected results are analyzed for subsequent reporting and/or corrective actions. Alert criteria may also be defined causing an alert to be issued if a significant fault is discovered.
